Embodiment Construction
[0023] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will be combined with the accompanying drawings to elaborate on the open pulverizing exhaust gas heating type boiler unit of the present invention.
[0024]
[0025] figure 1 It is a structural block diagram of the power generation system in the embodiment of the present invention.
[0026] Such as figure 1 As shown, the power generation system 100 includes: an open pulverizing exhaust air heating type boiler unit 501 , a steam turbine unit 502 , and a generator unit 503 .
[0027] The heat generated by the combustion of raw coal in the exhaust gas heating boiler unit 501 of the open pulverization process heats water to form high-temperature and high-pressure steam, which enters the steam turbine unit 502 to do work, and then drives the generator unit 503 to generate electricity.
[0028] figure 2 It is a structural block ...
